IMPROVMENT IN PADLOGKS.

TO ALL WHOM IT MAY GONOERN:

Be it known that I, JACOB E. KOHOUT, 'of Brooklyn, Kings county, andState of New York,ihave invented an Improved Padlock; and do herebydeclare that the following is a full and exact description thereof,refen ence 'being-had to the accompanying drawings, making part of thisspecication, in which- Figure luis an elevation, showing the shackle andhasp locked to the body of the padlock.

Figure 2, an edge view of same. I

Figure 3, an elevation of the padlock, with the hasp unlocked forreception of the key.

Figure 4 is a sectional elevation, showing the inner or working parts ofthe lock.

Figure 5, an inner view of the front plate, showing the device forlooking the hasp.

Figure 6, an elevation of the key.

Figure 7, a View .of the shackle, being released from the sliding bolts;and

Figures 8 and 9 are views of the trippcr, for preventing reversemovement of the key after locking and unlocking.V v

The nature of this invention consists in locking the liasp to thebody ofthe lock, by means of a lever and springs attached to the front plate,until it is desired to insert the key for the purpose of unlocking thepadlock, when, by pressing the said lever downward, the hasp is thrownoutward, exposing the key-hole of the lock; und also in a device placedbetween the sliding bolts, which obliges the key to move in one and thesame direction for locking and unlocking the padlock.

i In the accompanying drawings, representing the construction of myinvention, A is the case or body ci' the lock, C the shackle, and D thehasp, hinged to the front plate, E, oi` the padlock. This hasp has acatch, d, ou

its inner side, which passes over a bentlever, F, attachedto the innersideoi' the vplate E, said lever, with the spring G, for'holding thelever in position, (sec lig. 5,) constituting the locking-device of thehasp. H is the device placed betweenthe sliding bolts, for preventingretrograde movement of the key, consisting of the'stationary bed I,rectangular stop K, and' spring L, (seeigs. 8 und 9.) M M are thesliding bolts, which slide on pins m m, said'bolts being operated by`the key O and springs I? P. Itis the spring which throws'the shackleout of the lock on beingreleased from the sliding bolts.

The operation of my invention is as follows: My invention being locked,as shown in lig. 1, 1t is unlocked and operated as follows: By pressingthe bent lever` F, which extends a short distance outside of the case ofthe lock, downward, the catch el will be disengagedfrom the said lever,and the hasp D raised, (see iig. 3,) exposing the key-hole. New, byinserting the key O in the lock, und turning the key in one direction,the sliding bolts M M will be drawn back i'romthe shackle, and theshacklev pushed out of Ithe lock by the spring R; on which the shacklerests, when the said bolts will resume their former position, by beingimmediately pushed forward by the springs P P, the stop K dropped, so asto prevent return of the key; and my invention can be again locked bysimply pressing the shackle downward, when it will be embraced by thesliding bolts and locked, thereby rendering my padlock, as well as itshasp, self-locking. Y

Having described my invention, what I claim, and desire to secure byLetters Patent-,is-

1. The stop K and spring L, for preventing retrograde movementoi` thekey.

2. And, in combinationtherewith, I claim the sliding bolts M andshackle-spring Rf, all operating together, substantially as and for thepurposes describedund setvforth.

In testimony whereof, I havehereun-to set my signature, this lthpday ofJanuary, A. D. 1868.

' JACOB' E. KOHOUT.
